Berger Zinc Chromate Red Oxide Primer
Red oxide primer is a specially formulated coating used as a base coat for ferrous metals.
Berger Red oxide primer is formulated for interior and exterior use on ferrous metal and is not usually suitable for galvanized or nonferrous metals like aluminium, copper or brass. Ferrous metals contain iron. To confirm if your metal is ferrous or nonferrous, test it using a magnet. Ferrous metals are magnetic, and nonferrous metals are not. Berger Zinc Chromate Red oxide primer is an anti-corrosion coating, designed to stop rust formation. It can be applied directly over a rusty surface and is most ideal for exterior use. Red oxide primer can be coated with Berger 404, Rustpro or Machinery Enamel once dry.

Excellent adhesion
Anti-rust protection
Performs well inside and outSurface preparation:
- Ensure that all substrates are clean and free from grease or oil

- Remove all loose and flaking material by scraping with a paint scraper, wire brush or by sanding
- For some metals, flame cleaning or grit blasting may be necessary
Application Procedure:
- When applying red oxide primer, use a brush or a short pile roller Thinning is not required if applying by brush or roller
- For airless sprayer thin primer 10% to 15% by volume with Berger Reducer #2
- Begin thinning with as little solvent and add more as needed until the right consistency is achieved
- Spray red oxide primer onto the surface with a minimum working pressure of 2000 psi
- Apply 1 coat to provide an adequate base coat to your metal

Solve Potential Paint Problems
1What are those reddish-brown spots on my wood and walls?
Reddish-brown stains on the paint surface are called nail head rusting and are usually a sign that the surrounding wood may be rotting.
What are the possible causes?
- Non-galvanized iron nails exposed to moisture
- Nails not properly countersunk
- Nail heads not caulked with siliconized caulk before painting
- Frequent exposure to damp wood
What is the solution?
- Completely remove the nail and replace with a new nail
- Wire brush each nail head until bare shiny metal
- Clean and spot priming with appropriate Berger primer
- Caulk nail heads with paintable Berger acrylic caulk
- Topcoat with premium Berger acrylic or oil paint

2Why do I have a patchy paint finish?
Patchiness generally occurs when insufficient paint has been applied or when paint is applied unevenly, resulting in a variation of the film build leading to patches.
What are the possible causes?
- Inconsistent distribution of paint on the surface
- Incorrect or low quality paint brush or roller
- Failure to apply a primer over joint compound
- Applying paint over joint compound not fully dried
- The top coat is applied over spot-puttied surfaces
- Variations in surface gloss can cause paint to appear patchy
What is the solution?
- Increase the amount of paint on the brush or roller to allow better distribution
- Apply the paint in a grid fashion to ensure an even finish
- Allow puttied wall to dry evenly before priming
- By applying one coat of appropriate premium Berger Primer
- Apply two coats of premium Berger acrylic topcoat
- Refer to Berger Technical Support for primer options

3Why didn’t the paint hide the surface beneath in two coats as recommended?
Poor hiding occurs when paint fails to obscure or hide the surface to which it is applied.
What are the possible causes?
- Using low-quality paint with little hiding power
- Spreading paint too thinly or unevenly
- Over-thinning paint beyond the recommended amount
- Failure to prime the surface before top-coating
- Painting a porous or absorbent surface
- Using incorrect or poor quality tools
- Inadequately mixed paint
What is the solution?
- Prime first, if moving from a significantly darker to a light colour
- When painting in a dark colour, tint primer in a similar tone to the topcoat shade
- Use premium quality paint for better hiding and flow
- Use quality and correct tools for the job
- Follow manufacturer's recommendation for thinning
